BAROMETRIC CONDENSER.

oasnsc.

To all whom it may concern Be it known that 1, CHARLES L. W. TRINKS, aresident of Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement in BarometricCondensers, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, in which the figure is a vertical section ofa condenser embodying my invention with the tail broken away.

My invention has relation to barometric condensers of the countercurrenttype, and the object of the invention is to increase the efficiency ofthe condenser by providing means which insure the removal of a maximumamount of air from'the cooling water before the latter is heated, andalso to provide for thorough mixing of the water and steam, so that theoutgoing water will have as nearly as possible the temperature of theincoming steam.

The nature of my invention will be,

best understood by reference to the aocompanying drawings in which Ihave shown the preferred embodiment thereof and which will now bedescribed, it being premised, however, that various changes can be madein the details of construction and arrangement of the parts by thoseskilled in the art, without departing from the spirit and scope of myinvention as defined in the appended claims.

In these drawings, the numeral 2 designates the Walls of the condenserchamber; 3 the steam inlet which enters said chamber at one sideintermediate its upper and lower ends; 4 the exhaust connection at theupper end of the chamber to which is attached the usual exhaust pump forexhausting air from the condenser; and 5 the water inlet which opensinto the chamber at one side near the upper end thereof.

6 designates a baflie or weir of general frustoconical form, which isplaced in the -upper portion of the condenser chamber adjacent to thewater inlet. This baflie or weir ishollow and is open at its ends, theupper edge being curved inwardly, as shown at 7, to provide a wateroverflow. Placed below this battle is a splash plate 8, having aperforated central horizontal portion and being open at its peripheralportion, except for the supporting members 9. A short Specification ofLetters Patent.

I Application filed October 10, 1911. Serial No. 653,897.

condensing chamber in the manner illustrated in the drawing with aportion thereof perforated, as shown at 14. tance below this extendedupper wall of the steam pipe, which acts both as a splash plate for thewater and as a deflector for the steam, is another reverting flange 15.

16 designates an annular trough placed some distance belowthe revertingflange 15 and having an overflow edge 17. The trough 16 has perforations18 in its bottom, and also preferably has extending therethrough a shortvertical pipe 19.

The operation is as follows: Water-fall ing over the upper edge 7 of theweir 6.

strikes the splash plate 8, and is deflected with approximatelythree-fourths of its striking velocity against the lateral walls of thecondenser chamber through the open portions 9 of said late. A portion ofthe Water will also fall through the perforations in the central portionof the plate.

The water which is deflected outwardly against the lateral walls of thechamber is again'defiected inwardly and downwardly by coming in contactwith-the reverting flange or ring 10. This flange or ring pre- A shortdisvents the water hugging the wall and throws it back into the interiorof the vessel in a series of irregular impulses. 'In the space above thesplash plate 8 there is substantially little condensation of the steam,but air separation takes place to a considerable extent. Between thesplash plate 8 and the splash plate 11 still more air separation occursand also more condensation. The water revert-ed by the annular flange 10drops into a pool on the annular plate 11. a part of the water fallingthrough the holes 13 and another part flowing over the central edge 12.This overflow ed or weir is preferably rounded with a comture.

paratively large radius. The purpose of this rounding is to .prevent thewater fiow-' water strikes the plate 14, it splashes up in the formoffine drops and thus performs one step of the thorough mixing of thesteam and water. The principal condensation occurs below the plate 14:by the action of the run of water through the plate, by the waterdropping over the edge of the plate and by the water reverted by thering 15. The shape of the plate 14 is, as illustrated, such that nowater can enter the steam pipe. The water leaving the condenser chamberbelow the plate 14 is quite warm, but is not up to the steam tempera- Toincrease the temperature of the water still more, an additional cascadeis provided by the overflow edge of the trough 16, together with theperforations inthe bottom of said trough. The pipe 19 provides means foreasy access of the steam to the outer side of the cascade of waterflowing over the weir edge 17, steam rushing through this pipe and alsodown within this cascade by reason of the condensation which occurs.

In order to break up the water flowing over the several weir edges, orflanges, to insure the free escape of air and also to insure the properpassage of steam through the condenser, such weir edges are preferablyprovided with one or more lugs or projections 20. These lugs act asseparators for the water, leaving open spaces through which the steam orair can pass.

More or less air is always mixed with the steam which is removed by theviscous drag or friction of the water. If very much air enters with thesteam, this friction is not sufficient to removeall of it. In order totake care of this, I preferably provide a bypasspipe 21, having aregulating valve 22, therein, one end of this bypass communicating withthe condensing chamber below the trough 16 and the other endcommunicating with said chamber a short distance A below the splashplate 8. This byplass'pen mits air which may be present in t e lowerportion of the condensing chamber to be drawn upwardly therethrough andto be removed at the upper portion of the cham-v ber. Any steam whichmay be drawn up with the air will be condensed by the water adjacent tothe upper bypass connection. To insure this, I preferably provide adeflecting flange 23 immediately above the opening of this connection.By means of the valve 22, I am enabled to regulate the size of thebypass opening, and thereby prevent any excess of steam being drawntherethrough.

It will be obvious to those skilled in the art that my inventionprovides means for insuring a very thorough mixing of the water andsteam in a highly eflective manner, and that it also provides for theremoval of the air from the cooling water before the latter is heated.The condenser, there fore, operates with a high degree of efliciency.
